The rare earth element gadolinium is often used as a contrasting agent for MRIS. The concentration of gadolinium was measured in the discharge from a wastewater treatment plant near a large medical facility. Eight measurements were obtained: 1.254 ppm, 1.252 ppm, 1.246 ppm, 1.242 ppm, 1.815 ppm, 1.244 ppm, 1.251 ppm, 1.249 ppm. Use the Grubbs test to determine if one of these values is an outlier. What is the value of Geale? Should this potential outlier be rejected with 95% Geale = confidence? Critical values of G can be found in this table. TOOLS x10 The potential outlier should be rejected. The potential outlier should be kept. Based on the outcome of the Grubbs test, calculate the mean (x), standard deviation (s), and 99% confidence interval for the results. A list of t values can be found in the Student'st table. ppm S = ppm confidence interval: x+ ppm

Question
The rare earth element gadolinium is often used as a contrasting agent for MRIS. The concentration of gadolinium was measured in the discharge from a wastewater treatment plant near a large medical facility. Eight measurements were obtained: 1.254 ppm, 1.252 ppm, 1.246 ppm, 1.242 ppm, 1.815 ppm, 1.244 ppm, 1.251 ppm, 1.249 ppm. Use the Grubbs test to determine if one of these values is an outlier. What is the value of Geale? Should this potential outlier be rejected with 95% Gcalc = confidence? Critical values of G can be found in this table. + TOOLS x10 The potential outlier should be rejected. The potential outlier should be kept. Based on the outcome of the Grubbs test, calculate the mean (x), standard deviation (s), and 99% confidence interval for the results. A list of t values can be found in the Student'st table. ppm S = Ppm confidence interval: ppm
